Vessel designer Ulstein Design & Solutions has announced a new design for a hybrid-powered wind turbine installation vessel (WTIV).
The type Ulstein J102 zero-emission turbine installation vessel can operate 75% of the time in zero-emission mode while using a combination of hydrogen fuel cells and a small battery energy storage system (BESS). The combination aims to be sufficient to meet the overall power demand from on board equipment and peak crane loads. The hydrogen hybrid system of the Ulstein J102 design has been developed so that future developments in hydrogen technology can be fitted into the vessel without major modifications.
Hydrogen is one of the most promising zero-emission fuels for offshore vessels and Ulstein has decided to use it in developing sustainable ships, the yard said. The design aims to achieve an annual reduction in carbon dioxide emissions of 4,000 tonnes compared to comparative vessels now in service.
